STEERING DEVICE FOR POWER-BOATS.

SPECIFICATION forming part of Letters Patent No. 792,121, dated June 13, 1905.

Application filed August 31,1904. Serial No. 222,809.

To all whom it may concern:

Be it known that 1, James J. DONOVAN, a citizen of the United States, and a resident of Peabody, in the county of Essex and State of I Massachusetts, have invented certain new and useful Improvements in Steering Devices for Power-Boats,of which the following is a speciiication.

This invention relates to improvements in steering devices for power-boats; and itis carried out as follows, reference being had to the accompanying drawings, wherein Figure l is a plan view of the forward end of a power-boat with my improved steering device attached. Fig. 2 is a detail top plan view of the said steering device. Fig. 3 is a longitudinal section on the line 3 3 shown in Fig. 2. Fig. 4: is a cross-section on the line L4: shown in Fig. 2, and Fig. 5 is a cross-section on the line 5 5 shown in Fig. 2.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In Fig. 1, A represents the forward end of a power-boat, on which B is the forward deck portion, as usual.

G is the steering-wheel, attached in any suitable manner to the spindle D, the forward end of which is journaled in a bearing E, integral with which is a horizontal sleeve E, in which is guided a rod F, having a toothed rack F on its upper side engaging with a toothed pinion D, secured in a suitable manner to the forward end of the wheel-spindle D, as shown.

The rack-rod F is connected at its ends to cords G G, leading over suitable pulleys g g to the rear connecting device of the rudderpost in any suitable or well-known manner.

The ends of the sleeve E are journaled in blocks H H, adapted to be secured in any desired position, horizontally inclined or vertical to the deck or other portion of the boat, as may be desired. Each of said blocks H is slitted, as shown at h, Figs. 3 and 4, and provided with a clamping-screw H, by means ofwhich the sleeve E can be clamped firmly in any desired position, so as to hold the bearing E, its adjustable spindle D, and wheel C in any suitable position desired by the operator of the steering device. i V

The rear end of the bearing E is slitted at e and provided with a binder-screw I for the purpose of clamping the spindle D and its pinion D firmly in position whenever it is desired to hold the rudder in a central position while steering the boat in a linear direction, as may be desired in going in a straight course.

ff are stop projections secured to the ends of the rack-spindle F, so as to prevent the latter from being moved beyond the ends of the bearing-sleeve E during the turning of the wheel C. K is a removable shield secured to the bearing E for the protection of the pinion D from dust, &c.

WhatI wish to secure by Letters Patent and claim is- The herein-described steering device, con-
